Sigma has made a number of amendments to its lens compatibility notice for Sigma lenses when used on Canon's EOS R mirrorless camera.
After further testing, Sigma has concluded both autofocus and optical image stabilization (for applicable lenses) work 'without any issues' on the following lenses when used with Canon EOS R mirrorless cameras via the EF-EOS R mount adapter or Control Ring EF-EOS R mount adapter:

*Camera’s “Scene Intelligent Auto mode” cannot be used.
Sigma notes when Digital Lens Optimizer, located within the EOS R settings menu, is switched to 'OFF' but peripheral illumination correction, chromatic aberration correction and distortion correction are turned on, those corrections will be made for each lens, specific to their optical characteristics. 'This is applicable to DG and DC lenses from Contemporary, Art and Sports line listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later,' says Sigma in the press release.
Sigma also clarifies that any DC lenses where the image circle is made to match APS-C sensors is used, the EOS R won't automatically switch to its built-in 1.6x crop shooting mode, meaning it will have to be set manually. A future firmware update, expected to be 'announced at a later date,' will make this switch automatic and add support for the EOS R's Scene Intelligent Auto mode.
Testing also confirmed three lenses had the potential to show 'some phenomena' that required special handling. The Sigma 60-600mm F4.5-6.3 DG OS HSM, 24-70mm F2.8 DG OS HSM and 100-400mm F5-6.3 DG OS HSM all experienced a problem wherein on particular occasions the camera battery needed to be taken out and put back in place if the lens was removed while the optical stabilization is running.
Likewise, the 24-70mm F2.8 DG OS HSM and 100-400mm F5-6.3 DG OS HSM experienced an issue where autofocus would stop working from infinity to closer focus distance while shooting video.
Upcoming firmware updates to address these issues for these three lenses are expected 'at a later date.'
